Calibrating monitor

Eizo CG245W self calibrating monitor : Eizo Nanao Technologies Inc unveiled the Eizo ColorEdge CG245W, the first monitor in the graphics industry with a built-in calibration sensor and self-calibrating capability, at the NAB Show in the Las Vegas. Designed for pre-press, digital photography, video editing, and post production work, the 24.1" Eizo CG245W LCD monitor houses a built-in calibration device in its upper bezel that swings down at user-scheduled times. This eliminates the need for a third party external calibration device which must be manually placed over the monitor’s screen and then removed again every time calibration is performed. The Eizo self calibrating monitor is set to start shipping in the U.S. at the end of May.

Eizo calibrating monitor supports any Operating System
The computer itself is not necessary for self-calibration. By using the scheduling function in the on-screen display menu or the bundled ColorNavigator calibration software, the Eizo ColorEdge CG245W can be scheduled to self-calibrate at a specific time and at specific intervals including outside of work hours when the computer is turned off and the user is not present. Since self-calibration is performed independent of the computer, a calibrated Eizo monitor can be used with any operating system even if the OS is not supported by ColorNavigator.

To ensure calibration accuracy, EIZO calibrates each unit of the ColorEdge CG245W in the center of the screen before shipping and correlates the built-in sensor to these results. ColorNavigator includes a “Correlation Utility” that matches the measurement results of the Eizo ColorEdge CG245W’s built-in calibration sensor to those of an external calibration device. This may be necessary in a work environment where the Eizo ColorEdge CG245W is used with other monitors and all measurement results need to be standardized.

Eizo calibrating monitor incorporates IPS LCD panel Adobe RGB color space support
The Eizo ColorEdge CG245W monitor uses an IPS (in-plane switching) LCD panel with a native resolution of 1920 x 1200 (16:10 aspect ratio) and reproduces 98% of the Adobe RGB color space. The maximum brightness is 270 cd/m², contrast ratio is 850:1, and the viewing angles are 178°. One DisplayPort and dual DVI-I inputs are included. The DisplayPort input accepts 10-bit PC signals and can display 1.07 billion colors simultaneously from a pallet of 68 billion. This is 64 times more than the typical 16.7 million colors shown with 8-bit display.

ColorNavigator calibration software for Eizo calibrating monitor
The Eizo CG245W offers hardware calibration so the monitors themselves are calibrated rather than the computer’s graphics card. This ensures no color tones are lost in the calibration process and results in more predictable on-screen color. EIZO’s ColorNavigator calibration software is used for setting the target values for brightness, white point, and gamma and generating an ICC profile. EIZO’s Digital Uniformity Equalizer (DUE) function is included to counteract brightness and chroma uniformity errors that are characteristic of LCD panels. This ensures the Eizo monitor has a Delta-E difference of 3 or less across the entire screen.

To ensure proper display of brightness and color tones in various ambient environments and over the life of the monitor. The first is a new EIZO-patented function that stabilizes the brightness level after the monitor starts up or comes out of power saving mode. The second is an automatic brightness correction circuit that automatically corrects changes in the backlight’s brightness that occurs over time. The third feature counteracts the influence that changes in ambient temperature can have on the display of color tones. The Eizo ColorEdge CG245W includes an illuminated on-screen button guide that simplifies adjusting the OSD menu in a dimly lit working environment. It also offers six preset color modes that reproduce common color spaces used in pre-press, digital photography, broadcasting and digital cinema: Adobe RGB, sRGB, Rec709, EBU, SMPTE-C, and DCI.
